I usually thread the hole and put a set screw with red locktight, they also make a pinless for the forward accumulator too.

@scottmichaels1764 3 года назад

What you are doing to retain the steel ball in the accumulator housing is called "staking" not "crosshatch".

This help out alot, just finish doing mine haven't filled it with oil yet but I'll be sure to keep you posted.

Thanks for the video! Trying to help - correct me if I am wrong but more info might be needed at the end of this video. If you do not press the piston into the receiver further than you showed, the springs will be inside rattling around. I believe you need to soak/lube the crap out of the rings and then press the piston down until both rings of the piston pass the little bevel in the receiver. The piston will then be in contact with the springs and then it will move back and forth. Not sure the fluid in the tranny would get the rings set and the springs aligned if you left it to chance.

@martinez1701a 3 года назад

For that hard shift you also want to block that TCC regulator valve it could cause hard 1/2 shift also, I usually do all pinless in 4l60e along with TCC works great.

T45 works great 🎉

Hi so do u reuse the 2 old spring or buy new one

@B34RN4K3D 2 года назад

Would this be the same for a 91 k2500 with the 700r4? I'm having a very difficult time finding any straightforward information online.

@mafosa8519 3 года назад

I wasn’t buying that “ball n swedge deal” I just drilled the hole with a 5/16 drill bit. Tapped a 3/8-24 thread. Screwed in 3/8-24 - 3/8” set screw with red loc-tight. Still a good share! Larry

@howtofrank502 3 года назад

Thanks for sharing Larry! Been about 25k miles since the repair, no issues!

@budthechud3408 2 года назад

Anyone got a part number for the springs?

@michaeld4879 9 месяцев назад

Great video is this the same for the 700r4?

@johndeleon1462 4 года назад

I have a 2003 4l60e, wondering if replacing accumulator will fix my issue. Iam having a harsh shift from 1-2 but it’s not a hard thud shift, kind of like a soft but uneven smooth transition to 2nd. Is this about the same symptoms that would be considered to replacing the accumulator?????

@howtofrank502 4 года назад

Sounds like your accumulator to me! Mine wasn’t a “hard” shift, but it was uncomfortable to me (I’m very picky with transmissions lol)

@maxt3592 Год назад

It’s called staking the check ball and there’s nothing wrong with your accumulator you probably want to check your accumulator valve in the valve body👈🏻😎

@alexnguyen5444 3 года назад

Hey my accumulator only had 1 spring will this still work?

@howtofrank502 3 года назад

What year and model is your vehicle? If it only came with one, I assume that’s what it needs, should be just fine!

@mbravo9854 4 года назад

I have my pan off now and I suspect this to be my problem as well. do I have to worry about the valve body gasket when removing this unit??

@howtofrank502 4 года назад

nope, just the 3 bolts and you’ll be in good shape! Best of luck

@mbravo9854 4 года назад

great, thanks. and thanks for the reply. you can only get this upgraded piece only tho? autopart store don't have em ?

@howtofrank502 4 года назад

M Bravo They are available on Amazon, link is in my bio. I don’t think any auto parts stores carry these

@mbravo9854 4 года назад

cool thanks bro

@bajapanta1 4 года назад

I get what ur saying but what about the second steel ball they also give u is it just for fitting purposes or ?

@howtofrank502 4 года назад

Sorry for the late reply! The second ball is for a 700R4 transmission. This kit is universal, so it will work on a 4L60E and 700R4!

@bajapanta1 4 года назад

Okay thank u

@jeremys.4423 4 года назад

Is it adequate to punch the ball down inside the pinhole or is the cross hatch required?

@howtofrank502 4 года назад

Sorry for the late reply. While you have it open, please cross hatch it! If the ball pops out, the accumulator will fail. Plus that ball will disappear inside of your transmission fluid, could cause some damage!

@jeremys.4423 4 года назад

@@howtofrank502 all good! And thank you sir! I will cross hatch the ball when my sonnax kit comes.

@chefzackkasmar6767 3 года назад

Thank you!! Now that you have been driving with the new accumulator, is the harsh shift fixed? Thanks again!

@howtofrank502 3 года назад

Thanks for watching! Yes, the harsh shift has disappeared.

@raudelacanda7794 4 года назад

08 Tahoe 4l60E I did the upgrade today didn’t work for me . Do you know why my accumulator come with the inner spring only . Do I have to get another spring for this kit ?

@howtofrank502 4 года назад

Hey there! When removing your accumulator from the transmission, was there only one spring inside? It is okay to reuse them if necessary. The piston kit doesn’t come with replacement springs, but a entire accumulator will.

@raudelacanda7794 4 года назад

FrankiesFixit yes only one . I reused I put everything back but didn’t work for me . Now change from 1-2 higher rpm .

@raudelacanda7794 4 года назад

FrankiesFixit also replaces the tps sensor. It is not all the time the hard shift from 1-2 is only first drive after the car warms up shift Normally from 1-2. Any idea?

@howtofrank502 4 года назад

What’re the miles on your truck? It will be a firmer shift but nothing “hard.” I would check your A and B shift solenoids, one may be failing. Did you swap your filter?

@raudelacanda7794 4 года назад

FrankiesFixit 180k miles. Yes, new filter. Firm shifts not hard .no check engine light .

@johndeleon1462 4 года назад

It is only noticeable at low rpms around 3k, all other gears shift fine

@howtofrank502 4 года назад

john de leon hey there! Sorry for the late reply. This sounds like the accumulator May be your issue! Also replace your A and B solenoids, and filter while you’re in there.

@Miguelgarcia888 3 года назад

Hey John. My 2005 Silverado z71 does the same. It hard shifts from 1st to 2nd gear at low RPMs only. Did you figure out the problem?

@johndeleon1462 3 года назад

@@Miguelgarcia888 iam pretty confident that it is accumulator, and good idea to change solenoids whilepan is dropped just to make sure. I haven’t even done it yet and I still drive with transmission doing the exact same thing, and it has never been a major issue to me. I’ve prolly put 5k miles on it with this issue
